"Max Air Flow" and "Max Air Flow @ 4" Hose" — Explained

Applicable Model

Gyro Air G-700 Dust Processor

Dust processors typically list two types of airflow ratings in their specifications. Understanding the difference between them helps set accurate expectations for real-world performance.

Understanding the Two Airflow Ratings

Maximum (Unrestricted) Airflow

This is the highest possible CFM the blower can generate when not connected to any hoses, filters, or ducting. It reflects the blower's peak output at the inlet with zero resistance and represents the theoretical ceiling of the unit's airflow capability.

Real (Operational) CFM

This represents the actual airflow you can expect during normal use — when the unit is configured with typical components such as hoses, ducting, and filters attached. This rating offers a much more realistic performance benchmark for evaluating dust collection capability in a real workshop setup.

Gyro Air G-700 Airflow Performance

Max Airflow (No Restriction)

1,110 CFM

Blower at inlet, no hoses, filters, or ducting attached.

Real CFM @ 4" Hose (10'–20')

~700+ CFM

With 4" hose (10'–20' length) and filters attached — typical real-world use.

The ~700 CFM operational figure gives a more accurate expectation for real-world use — especially when evaluating the G-700's efficiency for fine dust collection and multi-tool setups. When comparing dust processors, always consider the real CFM rather than the unrestricted maximum.
